SAWING MACHINE.

Patented July 25, 1922.

Application filed June 27, 1921.r Serial No. 480,875.

To all whom t may concern:

Be it known that l, FLETCHER J. SCOTT, a citizen of the United States, residing at Hurdland, in the county of Knox, in the State of Missouri, have .invented a certain new and useful Improvement in Sawing Machines; and l do hereby `declare the following to be a full, clear, and enact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

This invention relates to a new and useful improvement in a cross-head for a sawing machine or for a'coupling which may be inserted in a connecting rod or pitman for a drag saw, and the principal object of this `invention is Lto provide' a means whereby the saw may be changedl to cut in either a horizontal or a vertical plane, and means whereby this may be easily and quickly accom plished. p

In the accompanying drawings Fig. 1 is a perspective view of my improved device with the saw in positionto cutV in a vertical plane. Fig. 2 is a view similar` to Fig. l with the saw arranged to cut in horizontal plane. Fig. 3 is a detail of the latch used to secure the pivoted member 6 in either of its two positions.

Referring more particularly to the drawing wherein like reference characters desig natelike parts. la represents a guide bar mounted a coupling or cross-head 2a capable of being reciprocated thereon by means of a pitman or connecting rodl 3C, which may be connected to a crank or any `other convenient reciprocating means. This pitman is pivotally mounted to the cross-head by pin 4. n i

Pivotally mounted on a pin 8 between two parallel guide bars on the cross-head is a member 6 provided witha rounded end kas shown in the drawing, which provides a convenient handle therefor. This member also contains two holes '9, one at each side of the pivot 8, into one of which one of the two y f Fig. 2. The latch 10 is mounted through an angular member ll, as clearly shown in Fig. 3, and provided with a spring 12 which tends to press the latch l0 into the groove in which the member 6 lies. This latch 10 is provided in duplicate on the cross-head, one being provided on 'the horizontal guide strip across the top of the cross-head and the other being provided onv the vertical guide strip, as clearly shown in F ig. 2.

Upon the pivoted member 6 is pivotally mounted as at 7 a saw carrying bar 5, which will turn with the member 6 to cause the saw to assume a position either in a horizontal or in a vertical plane.

It is apparent that the cross-head will reciprocate with a straight line motion and when it is desired to cut in a horizontal plane, as, for instance, in felling a tree, the member 6 will be placed as shown in Fig. 2 and held there by the latch l() which is on the upper or horizontal guide of the crosshead, whereas when the tree is felled and it is desired to cut in a vertical plane, as to out the tree into logs, it will merely be necessary to pull out the latch l0 holding the saw by the convenient and curved handle shown in Fig. 3 and liftthe member 6to vertical position, at the same time pulling out the latch. lO which is mounted on the vertical guide strip and letting it seat in the hole 9 nearest the end remote from the handle of the member 6.

l claim:

l. A. cross-head or guidedmeans constituting a connection between a means for producing reciprocating motion, and a saw reciprocated thereby, and an element pivoted to said cross-head on an aXis parallel to its reciprocating motion, to which element the saw is attached.

2. A. cross-head carrying a pivcted meinber, a saw carrying bar pivoted'to said member and shiftable therewith to change the plane of the sawk and means to retain the said member in either of two positions at right angles to each other.

FLETCHER J. SCOTT.
